85514881 ÷ 835 
The aim is to understand the frequency of 835 in 85514881.

Advancing to step 1:
8 divided by 835 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 835

Advancing to step 2:
835 goes into 85 0 times with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Append the next digit (5) from the dividend to 85 and continue with: 855 / 835

Step 3:
The number 835 fits into 855 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 835 from 855 leaves us with 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 835

Advancing to step 4:
835 goes into 201 0 times with a remainder of 201.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 201 and we're left with 201.
Take the next digit (4) from the dividend and append it to 201, then repeat: 2014 / 835

Advancing to step 5:
2014 divided by 835 is 2 with a remainder of 344.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 344 after subtracting 1670 from 2014.
Fetch the next digit (8) from the dividend, attach it to 344 and continue: 3448 / 835

Going ahead to step 6:
If we divide 3448 by 835, we get 4 and a remainder of 108.
The next digit of our result is 4. 
Result so far: 1024.0
Deduct 3340 from 3448 and we're left with 108.
Append the next digit (8) from the dividend to 108 and continue with: 1088 / 835

Going ahead to step 7:
The number 835 fits into 1088 1 times, leaving a remainder of 253.
Put 1 as the next digit of the answer. 
Result so far: 10241.0
If we subtract 835 from 1088, we get 253.
Fetch the next digit (1) from the dividend, attach it to 253 and continue: 2531 / 835

Advancing to step 8:
The number 835 fits into 2531 3 times, leaving a remainder of 26.
The next digit of our result is 3. 
Result so far: 102413.0
The remainder is 26 after subtracting 2505 from 2531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
260 divided by 835 is 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 102413.0
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
2600 divided by 835 is 3 with a remainder of 95.
Record the quotient 3 as the next digit in the result. 
Result so far: 102413.03
If we subtract 2505 from 2600, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 11:
950 divided by 835 is 1 with a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 102413.031
Subtracting 835 from 950 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 12:
When dividing 1150 by 835, we get 1 with a remainder of 315.
Write down 1 as next digit of the result. 
Result so far: 102413.0311
Subtracting 835 from 1150 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final result is 102413.0311 with a remainder of 0.00315.
